New Vaccines in SA Regulatory Perspectives James Southern 2015
Outline Regulatory Environment of new vaccines Clinical Trials Application procedures HIV Vaccines Other new vaccines in development Ongoing Actions September 2015 FUNDISA <=> New Vaccines 2
Regulatory Environment Act 101 of 1965 (as amended) Establishes Regulatory Authority All medicines must be registered for use in SA Quality Safety and Efficacy Medicines Control Council (MCC) Experts and stakeholders appointed by Minister of Health Expert Committees (Total=9) Clinical, P&A, Biologicals, Clinical Trials etc. Use Policies & Guidelines Recommendations to MCC New Amended Act (SAHPRA) being implemented Revise MCC and decision making Enhance evaluation capacity Include Medical Devices and diagnostics September 2015 FUNDISA <=> New Vaccines 3
New Vaccines - The Biological Medicines Committee Appointed by the Minister of Health Expert evaluators in Clinical use of biological medicines and vaccines Manufacturing and control of biological medicines Public Health Immunization Applications CTD dossier (Local Module-1) Evaluation reports peer reviewed by BMC Queries to applicants consolidate report Recommendation to MCC Approve or Reject Post Marketing Risk Management commitment Evaluation and approval of amendments Timelines variable First response from BMC 12 16 weeks Approval usually 9 to 12 months September 2015 FUNDISA <=> New Vaccines 4
New Vaccines - Background No local vaccine manufacturer All imports Local manufacture of DTP, OPV, BCG terminated by 2000 Clinical development mostly outside SA CTD dossier first sight for evaluators Pilot IND-like procedure for local vaccine developers New vaccine applications from Emerging manufacturers As new vaccines have become available They have been registered introduced into EPI when appropriate NAGI & DoH decision. & trials Public Health vaccine-budget doubles every few years September 2015 FUNDISA <=> New Vaccines 5
Introduction of New Vaccines Childhood Vaccines Expanded Program of Immunization (SA) Included DTP, OPV, Measles & BCG for infants in 1990s Hepatitis B sag (recombinant) 1996 Haemophilus influenzae B PRP-conjugate 1998 Intradermal BCG 2000 Pentavalent DTP-HepB- HiB 2010 Rotavirus (Rotateq and Rotarix) 2012 Pneumococcal PS-conjugate 2013 Hexavalent DTaP-HepB-HiB-IPV 2013 Human Papilloma Vaccines (adolescents) 2014 Measles-mumps-rubella planned September 2015 FUNDISA <=> New Vaccines 6
New Vaccines Clinical Trials Clinical Trials Committee Evaluates applications for individual trials (not IND) Evaluates amendments to approved trials Recommends approval to MCC Applications Defined format policies and guidelines for applicant Evaluation by expert peer review of reports by CTC Follow SA GCP Guidelines (2006) and policies Parallel process with Ethics Committee approval required GMO licence or other laws expected Investigational products require Sect 21 Permit for import & use Timelines: 1 st Response from CTC 8 weeks. Approval 12-16 weeks September 2015 FUNDISA <=> New Vaccines 7
New Vaccines HIV vaccine development HIV and AIDS are a major health challenge in SA State support for HIV-research includes SAAVI - SA AIDS Vaccine Initiative Vaccines are developed with international support Many HIV Trials conducted in SA since 1999 MCC HIV Vaccine Task Group Guidelines and policies 2003 Quality, Safety and ethical treatment of participants New and Novel Vaccines and regimens in trials DNA-prime-boost, Vectored vaccines, novel adjuvants September 2015 FUNDISA <=> New Vaccines 8
Other New Vaccines 19 new vaccine trials have been approved since Jan 2014 Include Pneumococcal conjugate vaccine in pregnant (HIV+) women Meningitis PS-conjugate vaccines Influenza vaccines new formulations and in pregnant (HIV+) women TB vaccines modified BCG or MTb, Adjuvanted protein vaccines DNA, Vectors and adjuvanted proteins (Clade C) HPV vaccines new formulations - regimen Rotavirus vaccines new formulation RSV vaccines early development HIV and TB vaccine trial sites are well established September 2015 FUNDISA <=> New Vaccines 9
Current Each vaccine brings new challenges for MCC Adaptive trial designs defined alternatives Inclusion of adolescents and infants and pregnant women Dose-escalation age-de-escalation Inclusion of healthy HIV+ participants in vaccine trials Calculations of power to detect AEs or protection Lack of established correlates of protection New immunological end-point tests unvalidated Open-ended storage of clinical samples for future research Clinical trial registry Inspection of Trial sites GCP Guidelines and inspection policy New vaccine applications from Emerging manufacturers September 2015 FUNDISA <=> New Vaccines 10
Ongoing Actions Implementation of SAPHRA reduce uncertainty Strengthened NRA Improved and updated policies and guidelines Emergency and Pandemic vaccine approvals Improved communications with public and industry Increased staff levels and training more evaluators Electronic document management system International and Regional cooperation WHO, EU (EDCTP) and US FDA (DAIDS, NIH) Developing Country Vaccine Regulators Network African Vaccine Regulators Forum NGOs:- BMGF, AERAS, PATH, IVI Strengthened National Biologicals Control Laboratory Improved pharmacovigilance for vaccines use September 2015 FUNDISA <=> New Vaccines 11
